Problems solved by technology

The traditional treatment drugs for IBD include aminosalicylic acid, antibiotics and corticosteroids, etc. Because of their low curative effect and large adverse reactions, patients often cannot tolerate them, resulting in certain limitations in clinical application.
The application of immunosuppressants such as azathioprine (AZA), 6-mercaptopurine (6-MP), methotrexate (MTX) and cyclosporine can make most IBD patients, especially intractable cases, obtain a certain degree of clinical However, these immunosuppressants still have the disadvantages of high toxicity, poor selectivity, and the possibility of secondary infection and teratogenicity, so the clinical application is still not ideal

Abstract

The present invention discloses a new medicine purpose of Clostridium butyricum and Bacillus coagulans, in particular relates to an application of Clostridium butyricum and Bacillus coagulans in preparing the medicine for curing inflammatory bowel diseases. The inflammatory bowel disease refers to an ulcerative colitis and a Crohn disease. The Clostridium butyricum is selected from but not limited to Clostridium butyricum, CGMCC and the preservation number is 0313.1; the Bacillus coagulans is selected from but not limited to Bacillus coagulans, CGMCC and the preservation number is 1270. The Clostridium butyricum and Bacillus coagulans as a single pharmaceutical active ingredient or a combined pharmaceutical active ingredient has significant curative effect on ulcerative colitis and Crohn's disease, pertaining to the art of biological medicine.

Description

technical field [0001] The present invention relates to the new application of Clostridium butyricum and Bacillus coagulans, in particular to Clostridium butyricum and Bacillus coagulans alone or in combination as active ingredients in the preparation of medicines for treating inflammatory bowel disease, i.e. ulcerative colitis and Crohn's disease The application in the invention belongs to the field of biopharmaceuticals. Background technique [0002] Inflammatory bowel disease (IBD) is a general term for ulcerative colitis (UC) and Crohn's disease (CD), and traditional medicine believes that the cause is unknown. Ulcerative colitis is a non-specific chronic colitis. The lesions are mainly limited to the mucosa and submucosa of the colon. Colon, clinically manifested as persistent or recurrent mucus and bloody stools accompanied by abdominal pain, may have different degrees of systemic symptoms, such as joints, skin, eyes, mouth, liver and gallbladder and other extraintest...
